  input,
  weight
)[source]¶

Apply parametric rectified linear unit to input. [He et.al, 2015].

The PReLU function is defined as:

\[\text{PReLU}(x) = \begin{cases} x, & \text{ if } x \geq 0 \\ weight * x, & \text{ otherwise } \end{cases} \]

Parameters:

• input (dragon.vm.torch.Tensor) – The input tensor.
• weight (dragon.vm.torch.Tensor) – The weight tensor.

Returns:

dragon.vm.torch.Tensor – The output tensor.
